- How does the anti Blokier system (ABS) in motor vehicles?
Use in your statement, the terms static and dynamic friction. - A person goes from the ground floor to the first floor. Calculate the work that needs to apply that person.
length of the horizontal distance: 26m
length of the staircase: 12m height difference
7m
mass of the person: 80kg
gravitational acceleration g: ~ 10ms -2 - Two particles with the same mass collide. It is an elastic collision and the second particle is in rest at the beginning.
point the equation for the energy and angular momentum conservation, and simplify them. - Explain the Hooke's Law. Give the formula, the units and sizes.
